Description

Technical Field

[0001] The present invention relates to the field of pathogen sampling, and particularly to a respiratory pathogen sampling device and method. Background Art

[0002] Respiratory pathogen sampling is an important step for diagnosing respiratory diseases, mainly including various sampling methods such as nasal swabs, throat swabs, and bronchoalveolar lavage fluid. Throat swabs are a relatively common sampling method for collecting samples from the upper respiratory tract. It involves using a special swab (usually a cotton swab) to gently wipe inside the pharynx, then placing it in a test tube containing a culture medium or preservation solution, and then proceeding with subsequent pathogen detection.

[0003] During the sampling process of traditional throat swab respiratory pathogen sampling devices, the swab is always in an exposed state, and long-term exposure to the air easily causes secondary contamination of the sample. At the same time, during centralized sampling, due to a large number of samples collected and strong personnel mobility, there will be a phenomenon of sampling information deviation, resulting in the detection result not matching the patient, affecting the accuracy of diagnosis.

[0017] Figure 2 It is a sectional view schematic diagram of the present invention.

[0018] Each reference numeral in the figure is: tube body 1, sampling swab 2, sampling tube 3, screwing locking ring 4, limiting tube 5, movable pressing handle 6, spring 7, piston 8, auxiliary plug 9, dividing block 10. Detailed Description of the Invention

[0019] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0020] The applicant believes that during the sampling process of the traditional pharyngeal swab respiratory pathogen sampling device, the swab is always in an exposed state, and long-term exposure in the air easily causes secondary contamination of the sample. At the same time, during centralized sampling, due to a large number of samples collected and strong personnel mobility, there will be a phenomenon of sampling information deviation, resulting in a mismatch between the test result and the patient, affecting the diagnostic accuracy.

[0021] Therefore, the applicant designs a respiratory pathogen sampling device and method. Through the provided sampling assembly, the exposure time of the sampling swab 2 in the air is greatly reduced during the sampling process, and the risk of secondary contamination of the sample is reduced. At the same time, by cooperating with a dual information verification method, the matching consistency of patient information and sample information is ensured, and the diagnostic accuracy is further improved.

[0022] The respiratory pathogen sampling device involved in the present invention mainly includes two parts: a sampling component and a sampling tube 3. Among them, the sampling component includes a tube body 1 with a predetermined working length, which is hollow and open at both ends, and is provided with a carrying cavity of a predetermined working size for corresponding carrying operations; a sampling swab 2 movably connected to the tube body 1, with one end extending into the carrying cavity of the tube body 1 and the other end extending to a predetermined working distance outside the tube body 1. The sampling tube 3 is movably connected to the tube body 1, has a predetermined working length and a carrying space, is hollow and open at one end, and can perform corresponding carrying operations. The tube body 1 has a predetermined toughness, and a screwing locking ring 4 is provided on the surface of the working surface. In a further preferred embodiment, both the tube body 1 and the sampling tube 3 are made of PVC material. The tube body 1 is threadedly connected to the sampling tube 3, and during the later operation process, the tube body 1 and the sampling tube 3 can be separated by screwing.

[0023] A limiting tube 5 with a predetermined working length is provided in the carrying cavity of the tube body 1; the limiting tube 5 has a predetermined working length and a supporting force, is hollow and open at both ends. The overall working length of the limiting tube 5 is less than the overall working length of the tube body 1, and the sampling swab 2 can pass through the limiting tube 5 and extend to a predetermined working position outside the limiting tube 5. In a further preferred embodiment, in the initial operation state, the sampling part of the sampling swab 2, that is, the sampling cotton part, is placed in the hollow chamber of the limiting tube 5. The limiting tube 5 has a predetermined working thickness, and during the later operation process, the movement adjustment range of the sampling swab 2 can be limited by the working position of the limiting tube 5, that is, the movement range of the sampling swab 2 is the distance between the upper end position in the working direction of the limiting tube 5 and the upper end position in the working direction of the tube body 1. During the later operation process, when the sampling swab 2 moves and adjusts towards the direction close to the limiting tube 5, the sampling swab 2 can pass through the limiting tube 5 and the tube body 1 and extend to a predetermined working position outside the tube body 1 to ensure that the sampling cotton of the sampling swab 2 is completely exposed. The working size of the hollow chamber of the limiting tube 5 is larger than the overall working size of the sampling cotton provided on the sampling swab 2, so that the sampling swab 2 can flexibly pass through the limiting tube 5.

[0024] At one end of the sampling swab 2 away from the limiting tube 5, there is a movable pressing handle 6, which extends outside the tube body 1 through the movable pressing handle 6; the movable pressing handle 6 is movably arranged in the bearing cavity of the tube body 1 and can be adjusted within a predetermined range of movement in the bearing cavity of the tube body 1. The working sizes of the two open ends of the tube body 1 are different, and the screwing locking ring 4 is placed at one end of the tube body 1 close to the sampling tube 3 and is threadedly connected to the tube body 1. In a further preferred embodiment, the tube body 1 is in the shape of a micro horn, that is, one of the two open ends of the tube body 1 is narrow and the other is wide. The limiting tube 5 is also in the shape of a micro horn, and the overall working size is adapted to the working size of the bearing cavity provided in the tube body 1. The movable pressing handle 6 includes a clamping end and an extending pressing end. The clamping end is in the shape of a horn with both ends open, and the wide end of the provided clamping end is clamped in the bearing cavity of the tube body 1 and is placed at the narrow end of the tube body 1. That is, the working size of the wide end of the movable pressing handle 6 is larger than the working size of the narrow end of the tube body 1, so that the movable pressing handle 6 can perform corresponding movable pressing adjustment operations in the bearing cavity of the tube body 1. One end of the extending pressing end provided on the movable pressing handle 6 is open and is communicated with the clamping end, has a predetermined working length, is provided with a hollow chamber with a predetermined working length, and extends from the narrow end of the open end provided on the tube body 1 to a predetermined working position of the tube body 1. One end of the sampling swab 2 passes through the clamping end provided on the movable pressing handle 6 and is inserted into the hollow chamber of the provided extending pressing end, so that the sampling swab 2 is fixedly limited through the provided extending pressing end.

[0025] A compression spring 7 with a predetermined working length is provided between the movable pressing handle 6 and the limiting tube 5. The compression spring 7 is placed in the bearing cavity of the tube body 1 and has a predetermined deformability. The sampling swab 2 is fixedly connected to the movable pressing handle 6 and can be adjusted to the corresponding working position following the movement of the movable pressing handle 6 and can pass through the limiting tube 5. The compression spring 7 has a predetermined working size, and the sampling swab 2 can pass through the compression spring 7 and extend into the hollow chamber of the limiting tube 5. In the initial working state, the movable pressing handle 6 is pushed up by the compression spring 7. During the subsequent working process, when corresponding sampling operations are required, only need to press the extended pressing end provided on the movable pressing handle 6 in the direction close to the limiting tube 5, push the clamping end provided on the movable pressing handle 6 to move in the direction close to the limiting tube 5, so that the compression spring 7 is squeezed. Thereby, the sampling end of the sampling swab 2 is pushed out of the tube body 1, and the sampling cotton provided on the sampling swab 2 is exposed, so that corresponding pathogen sampling operations can be carried out. During the sampling process, it is necessary to continuously maintain the pressing state of the movable pressing handle 6. When the sampling operation is completed, only need to release the movable pressing handle 6, and then the compression spring 7 stretches and resets, pushing up the movable pressing handle 6 again, and at the same time driving the sampling swab 2 to move and adjust in the direction close to the movable pressing handle 6, so that the sampling cotton provided on the sampling swab 2 is driven back into the hollow chamber of the limiting tube 5, avoiding the sampling cotton being exposed to the air for a long time and being secondarily polluted.

[0026] A piston 8 with a predetermined working size is provided at the open end of the sampling tube 3. The piston 8 is adapted to the size of the open end of the sampling tube 3 and is provided with a protruding auxiliary plug 9. The auxiliary plug 9 has a predetermined working length and can extend into the hollow chamber of the limiting tube 5 through the open end provided on the tube body 1. In a further preferred embodiment, the auxiliary plug 9 can be threadedly connected to the sampling tube 3, and during the subsequent working process, the piston 8 can be separated from the sampling tube 3 by screwing the auxiliary plug 9 to drive the piston 8 to rotate. The piston 8 can also be integrally formed and cast at the open end provided on the sampling tube 3, and a dividing line is reserved. During the subsequent working process, the piston 8 with the reserved division can be separated from the sampling tube 3 by pulling the auxiliary plug 9. In the initial working state, the auxiliary plug 9 extends into the limiting tube 5, and thus in the initial working state, one end of the sampling swab 2 is subjected to corresponding sealing treatment through the movable pressing handle 6, and the other end is subjected to corresponding sealing treatment through the auxiliary plug 9, so that the sampling swab 2 can be stored in a sealed environment to avoid the sampling swab 2 in the unused state being contaminated.

[0027] A partition block 10 is provided in the hollow chamber of the limiting tube 5. There are multiple partition blocks 10, which are evenly distributed on the inner wall surface of the hollow chamber of the limiting tube 5. In a further preferred embodiment, an external thread with a predetermined working length is provided on the working surface of the tube body 1, and the screwing locking ring 4 is provided with a corresponding internal thread. The screwing locking ring 4 is threadedly connected to the external thread provided on the tube body 1, and the working size of the screwing locking ring 4 is adapted to the working size at the predetermined working position of the tube body 1. At the same time, the screwing locking ring 4 is made of hard plastic. Since the tube body 1 is in a micro-trumpet shape, and the end close to the sampling tube 3 is a wide-mouth end, and at the same time, since the tube body 1 has a predetermined toughness, the screwing locking ring 4 can be screwed and adjusted in the direction close to the sampling tube 3, so that the wide-mouth end of the sampling tube 3 is forced to tighten under the restriction of the screwing locking ring 4, and thus multiple partition blocks 10 can be tightened together, and the sampling tube 3 of the sampling swab 2 can be squeezed and divided.

[0028] In a further preferred embodiment, a corresponding dividing line is reserved at a predetermined position of the sampling tube 3 of the sampling swab 2. The working position of the dividing line provided on the sampling swab 2 corresponds to the working position of the provided partition block 10 in the initial working state of the sampling swab 2. The specific structure of the sampling swab 2 can refer to the prior art, that is, it includes two parts: a sampling tube 3 and sampling cotton, and a dividing line is reserved at a predetermined position of the sampling tube 3.

[0029] Based on the above respiratory pathogen sampling device, the present invention proposes a sampling method for a respiratory pathogen sampling device, and the specific steps are as follows: First, separate the sampling tube 3 from the sampling assembly by screwing, and place the sampling tube 3 on the storage rack for standby; Next, press the movable pressing handle 6 to squeeze the compression spring 7, drive the sampling swab 2 to penetrate through the limiting tube 5, and make the sampling swab 2 extend outside the tube body 1. Place the sampling end of the sampling swab 2, that is, the sampling cotton, at the respiratory pharynx of the patient for wiping and sampling; Then, after sampling, release the movable pressing handle 6, the compression spring 7 resets, and at the same time, the sampling swab 2 is retracted into the carrying cavity of the tube body 1; Subsequently, pull out the piston 8 through the auxiliary plug 9 to expose the open end of the sampling tube 3, and connect the sampling assembly to the sampling tube 3 again; Next, screw the provided screwing locking ring 4 so that the tube body 1 and the limiting tube 5 are squeezed and tightened, driving the multiple partition blocks 10 provided on the limiting tube 5 to tighten together, cut and separate the sampling end of the sampling swab 2, so that the sampling end of the sampling swab 2 falls into the sampling tube 3; Finally, send the whole sampling device after sampling to the inspection department for further pathogen detection and processing.

[0030] The sampling tube 3 contains a virus preservation solution, which can denature proteins in fresh clinical virus specimens to inactivate the virus, prevent secondary transmission and infection, and ensure the safety of transportation and testing personnel. This is the prior art and will not be elaborated in this application.

[0031] A two-dimensional code is provided on the working surface of the sampling assembly. This two-dimensional code contains the coding information of the sampling device. Before the sampling operation, the two-dimensional code needs to be scanned first to input the corresponding coding information of the sampling device, and then the patient information is input through the background program to generate a corresponding barcode and print it out. The printed barcode information is pasted on the working surface of the sampling tube 3. After the sampling operation is completed, when the sampling device is transported to the laboratory, the barcode on the working surface of the sampling tube 3 is scanned first to input the patient information into the background system, and then the two-dimensional code provided on the working surface of the sampling assembly is scanned to check the coding information of the sampling device to ensure the matching accuracy between the pathogen detection and processing results in the sampling device and the patient information.

[0032] After the sampling device is transported to the laboratory, the specific steps for matching and comparing the coding information of the sampling device with the patient information by scanning include: First, scan the barcode pasted on the working surface of the sampling tube 3 to input the corresponding patient information into the background system, including the patient's name, gender, age, sampling time, and the coding information of the corresponding sampling device; Then, the background system performs data cleaning on the input patient information data, sets the coding information of the corresponding sampling device as the target data , and filters and shields the remaining data information; Next, scan the two-dimensional code provided on the working surface of the sampling assembly to obtain the coding information of the sampling device contained in the two-dimensional code ; Compare with and output the corresponding comparison result: ; where Match(x) is the matching output result; Finally, when the matching output result is 1, it means that the coding information of the sampling device is verified correctly and subsequent pathogen detection and processing can be carried out; when the matching output result is 0, it means that there is an abnormality in the verification of the coding information of the sampling device and further information verification is required.
